Crack sealing has received considerable interest in the U.S. in recent years. In states like Louisiana, 70% of the districts use crack sealing for pavement preservation with average annual expenditure of about $91,000 per district as in 2016. Although this is a relatively significant expenditure, the optimum timing of crack sealing application ...

Crack sealing is the process of placing an adhesive sealant into cracks on the pavement surface, preventing the infiltration of moisture and non-compressible materials into the pavement. It is a cost-effective pavement preservation treatment that can slow pavement's deterioration and extend pavement life by three to five years.

Cracks in pavement surfaces must be filled to prevent water penetration damage. Classic Seal Coating and Paving uses the highest quality rubberized crack sealant which forms a resilient and adhesive compound that will seal joints and cracks against the infiltration of moisture.

Crack sealing will extend the life of your asphalt. GPM follows a multi-step process to ensure a lasting, durable result: First the crack is thoroughly cleaned of all dirt, dust, and debris using an industrial air compressor. If necessary, an environmentally friendly herbicide is applied. Next, the crack is sealed.

Shapiro also recommends using a more flexible sealant on pavements with less than 20 percent crack density, and a stiffer sealant on pavements with higher crack density. "Crack density is measured by looking at a 10-foot-by-10-foot section of the road or parking lot that best represents the average condition of the entire pavement," Shapiro ...

proper pavements for crack sealing is critical to ensure the preservation and extension of the life of the pavement. Since crack sealing is a preventive Research Product 0-406 -P3 maintenance technique that adds no struc-tural capacity to pavement, ideal pavement

Effectiveness of Crack Sealing/Filling N Pavement performance: The IRI and pavement surface crack evaluation showed that the crack sealing/filling sections performed slightly better than the do-nothing section. The Load Transfer Efficiency (LTE) and asphalt modulus results showed that the crack sealing/filling sections did not

Sealing cracks quickly after they develop reduces the damage to the pavement. The longer the cracks remains sealed, the longer the pavement will perform. Visually inspect pavements every year to identify and seal new cracks. Cracks greater than 1/8" (3 mm) must be sealed to achieve the best protection of the pavement.
